COVER FOR FLOORr-SUMPS.

Application filed March 1, 1919.

To all whom it may concern:

Be it known that I, EDWARD W. N. Boosnr, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Covers for Floor-Sumps, anddeclare the followingto be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to covers for floor sumps, and its object is toprovide a simple and efficient construction of a cover for a sump formedof a crock body, the cover being adapted to be connected with the ventand discharge lines and provided with means of calking the said lines tothe cover and avoiding the necessity of forming apertures in the crockbody for such purpose as has heretofore been the usual practice. Inprevious sumps formed of crock a fiat cover has been provided having areservoir in the nature of a trap preventing a backfiow of gas from thecrock but, in such previous constructions, it is necessary to break theside of the crock for introduction of the vent and overflow lines, etc.,resulting oftentimes in the fracturing of the body and also increasingthe cost of installation. An object of this invention is to provide ametal cover having apertures by means of which the necessary vent andoverflow lines, etc., may be calked in position on the cover as ishereinafter more fully described and claimed. The preferred form of theinvention is shown 1n the accompanying drawings in which Figure 1 is aplan view showing my improved. cover in position on a crock body.

Fig. 2 is a vertical central section thereof.

Fig. 3 is a vertical section showing an alternative form ofconstruction.

Heretofore it has been usual to place the upper end of the crock sump inthe floor. In the use of my improved cover, the crock body 1 ispositioned below the floor line as shown clearly in Fig. 2, and a cover3 is pro vided therefor having a circular base portion fitting theshoulder at the upper end of the crock and an offset tubular portion 4:extending upward to the floor surface. This portion 4 has an upperenlarged end 5 adapted to receive the usual trap member 6 andfora-envious cover plate '7 therefor as Specification of Letters Eatent.

- shown. The vertical axis of this upright tubular portion 4 iseccentric to the axis of the cover as will be clearly understood fromFig. 1, and the cover on one side of the tubular portion is providedwith a series of apertures 8 having a recess formed there' about for thelead calking 9 by means of which a pipe 10 insertible through theaperture may be calked in position to prevent an escape of water throughthe pipe aperture. The number of apertures 8 may be varied depending onthe number of pipes calked in the apertures 8 therefor, the member 3 iscovered with cement 16 sealing the crock at the upper end and preventingan escape of water therefrom. It is also to be noted that the tubularmember 4 or 15, as shown in Figs. 2 and 3 respectively, may be providedwith a trap reservoir as is-shown in Fig. 2, or with merely the ordinarygrating 7 as shown in Fig. 3, there being many uses for the device inwhich a trap reservoir is unnecessary. It is therefore to be understoodthat the type of cover for the tubular portion whether integral orseparate from the cover member is not material to this invention.

This sump is particularly useful in garages and places where oil andgasolene or grease from sinks, etc., may Wash into the sump and, for thepurpose of recovering oil, etc., I provide the cover with a pump 13(which may be of any approved form) hav ing a barrel extending below thelower surface of the cover 3. By this means, oil

may be drawn off from the sump previous to possibility of its overflowthrough the discharge pipe 10 as will be readily understood. By means ofthe vent mentioned, the gaseous vapors arising from the sump may be discharged therefrom, the trap reservoir 6 preventing the discharge throughthe grating 7 The member 4: may be made integral with the" cover member3 shown in Fig. 2

separate therefrom as indicated in Fig. 3.

I In this latter construction the cover 3 is provided with an aperture14 at one side of the center of the cover, and a member 15 similar inall respects to the member A may be calked in position on the cover asshown. The cover in other respects corresponds to the cover shown inFig. 3.

By the construction of a cover as described, a crock sump may beutilized providing an inexpensive installation that is fully asefficient as an all metal type.

Having thus briefly described my invention, what I claim is 1. A coverfor sumps consisting of a base member having flanged apertures adjacentone side for calking of a pipe member thereto and an integral tubularportion positioned 'eccentrically ol the cover and opening therethrough,the said tubular portion being adapted to receive an apertured cover,and a trap reservoir therebeneath.

2. A cover for floor sumps consisting of a tubular portion openingthrough the floor and provided with the usual trap reservoir at themouth, and a cover member at the loWer end for the sump body adapted tobe calked thereto and provided with flanged apertures for dischargepiping, and an aperture for attaching a pump or the like thereto.

3; A sump cover comprising a cover member having a comparatively largeaperture positioned at one side of the center of the cover and a seriesof smaller apertures through which the piping may be connected,

a tubular member calked to the said aperture, the tubular memberextending upward to the floor line and provided with the usual gratingand trap reservoir.

4-. A metal sump cover for crock sumps consisting of a tubular memberhaving the upper end positioned at the floor line and extendingtherebelow and a base member adapted to be sealed to the end of thecrock body, the base member having one or more apertures at one side ofthe tubular member for introduction of the usual piping, the

, fication.

on one side for connection with a vent line,

the crock being adapted to receive the said base in sealed relationtherewith;

6. A cover for floor sumps consisting of a base member havin an apertureadjacent one side for the callring of a pipe member thereto, a tubularportion positioned eccentrically of the cover and opening therethroughand extending to the floorline providing an inlet for the sump, a trapreservoir for the said inlet member, and an apertured hub formed in theside of the tubular portion for the connection of a vent pipe.

7. A floor sump consisting of a crock member having a bell end and acover member adapted to be (cemented therein, the cover membercomprising a base and a tubular portion opening through the base andextendingto the floor line to provide an inlet, the tubular member beingeccentric-ally positioned on the said base, and the base being providedwith an aperture for calking an outlet pipe thereto.

8. A cover for sumps consisting of a base having flanged aperturesadjacent one side for calking pipe members thereto, a tubular portionatone side 01" the apertures eccentrically of the cover and openingthrough the base, an apertured cover for the said tubular portion, and atrap reservoir therein beneath the cover, In testlmony whereof, I signthls speci- EDWARD W. N. BOOSEY.
